Scaling the matrix

Scaling the matrix
#1
On to the next of the topics I’m uncovering as I delve further into the world of LDraw!

I was building a Technic model and discovered that one of my beams didn’t quite fit onto the pins it’s supposed to—it needed to be “stretched” just a bit (as is common with Technic models with odd angles and connections). I compared my model to another user’s, and I noticed that in his, the beam fit correctly even though all the geometry was the same in both models. I discovered that he had scaled some of the values in the matrix; I copied those values to my beam, and it worked!

So the question simply is, when this situation arises, how do I determine which values to scale in the matrix? Typically I’ll just need to make a part longer or shorter or taller by a small fraction. Can I do this interactively in LDCad, or do I just calculate scale factors based on the distance I need (and how do I know which boxes are the correct ones to change)?
